GAS AND ELECTRIC HEAT RADIATOR.

Application filed February 25, 1928, Serial No. 257,028, and in Great Britain April 6, 1927;

This invention relates to that class of means in which a gas or electric heated element is employed as a radiator for various purposes, such for example as food cooking, and more particularly to apparatus or stoves in which at least two radiators are Vertically arranged and means are provided to enable the distance that separates them to be altered at will. 1

According to the present invention, for the purpose of securing radiator movement the radiator is pivotally supported by a hollow or tubular member adapted to move, or to be moved, horizontally through a suitable angle, the radiator being furthermore connected to a link which forms with the hollow or tubular member a quadrilateral linkage system adapted to constrain the movement of the radiator in any desired way. The linkage system may be one producing parallel motion, or alternatively one that causes the radiator to become inclined towards a companion radiator as and for the purpose set forth in the specification of my Letters Patent No. 1,610,370, dated 14th December, 1926, or again the radiator may beinclined in the opposite sense it this should for any reason be advantageous or desired. The hollow or tubular member in one case conducts gas to the radiator and in the other case carries the wires which conduct electricity to the radiator; the same constructional form of hollow or tubular member may be used for each purpose if desired although in other instances each may be made for its own particular purpose.

A single movable radiator may be employed in an oven or cooking chamber in as sociation with a stationary radiator but preferably two oppositely arranged movable radiators will be employed. The radiator, or each radiator, may be moved by exerting an effort directly thereupon or upon the linked system which may for that purpose be extended to within easy reach outside the oven. Also when two movable radiators are employed they may be interconnected for simultaneous movement.

In a gas cooker according to the invention, radiators constructed in a manner analogous to that described'in the specification of my Letters Patent No. 1,639,605, dated 16th August, 1927, may be usefully employed. In all cases, whether gas or electricity be the heating medium employed, it may if desired, be arranged that the radiators when wide apart in extreme positions shall be housed in recesses in the walls of the chamber so that the front faces ofthe radiators are SllbStZll'l-r tially coincident with the said walls, thus glvmg maximum cooking space. The recesses need not in most cases exceed in depth the thickness of the lagging usually employed in cooking stoves, and lagging of equivalent or other desired thickness may be applied to the outside of the chamber to back the recesses and reduce heat losses. But in order that the invention may be more readily understood and easily carried into effect two arrangements are more or less diagramn'iatically illustrated in the ac companying drawings, these serving as examples from which other modificationswill be ascertainable.

Of these drawings, Fig. 1 is a sectional slde elevation of part of an electric cooker, Fig. 2 being a sectional plan corresponding thereto. views of part of a gas cooker.

Referring first to Figs. 1 and 2 a radiator 1 is employed having a downwardly directed tubular branch 2 extending through a slot 3 in the bottom l of an oven 5. This branch 2 fits swivel-wise over the spigot end of an elbow 6 forming part of a hollow or tubular member 7 the opposite end whereof is also shaped as an elbow 8 fitting swivel- Wise within a stationary bracket 9. 10 is a lug on the branch 2 and 12 is a lug on the bracket 9, which are linked together by a tie 13, thus forming a parallel motion system. As will be clear, the radiator can move above the member 7 14; is a recess in the wall of the oven into which the radiator 1 can be moved when desired. The electric conductors can be passed into the bracket 9 through any suitable opening such as that shown at 9. It will of course be understood that in general two radiators such illustrated will be employed in an oven.

In Figs. 3 and 4 the arrangement diiiers chlefiy from that of Figs. 1 and 2 in that the stationary pivot for the member 7 is located near the front of the oven instead of at the rear, being constituted by the up turned branch end 9 of a "1' piece 15, constituting a gas mixing chamber the tie 13 being extended so as to form a handle 16 whereby the radiator can be moved from without.

Whereas in Figs. 1. and 2 the linkage system is designed to cause the radiator to re- Figs. 3 and 4; are corresponding main parallel tothe adjacent wall of the oven whilst being moved towards or away from it, in Figs. 3 and at the distance separating the link pivot at 10from the associated pivot at 2 of the toothed or tubular member 7 has been made less than the distance separating the remaining pair of pivots so that the radiator may be angularly displaced in moving from say the position represented by the dot and dash line a; in Fig. 4 to the other dotand dash line g in said figure, the extent to which the radiators become inclined to one another being determined by .the difference in the distance separating the pivots of the linkage system.

What I claim is 1. In means of the kind referred to, a radiator, a hollow member pivotally supported at one end, upon which member the radiator is in turn pivotally mounted, and a link articulated to the radiator, forming with the said member a quadrilateral linkagesystem by which movement of the radiator is horizontally restrained.

2. In means of the kind referred'to, a

vertically arranged radiator, a member movableangularly in a horizontal plane upon which member the radiator is pivotally mounted, and means whereby the radiator is caused to occupy different angular positions in relation to the supporting member as the latter is horizontally moved.

3. In means of the kind referred to, a vertically arranged radiator, a member movable angularly in a horizontal plane upon which member the radiator is pivotally mounted, and a link articulated to the radiatorforming with the supporting memher a parallel motion system constraining movement of'the radiator as the supporting member is angularly displaced.

4. In means of the kind referred to, a vertically arranged radiator having a downwardly directed tubular branch, a stationary and hollow bracket, a hollow member arranged substantially horizontally having at one end an upwardly directed elbow upon which the radiator branch' aforesaid fits swivel-wise and at the o )ositc end a downwardly directed elbow W 11011 fits swivcl-\\'ise within the bracket, a lug on the radiator tubular branch, a lug on the bracket and a tie linking said 111 together.

5. Means accor ing to claim 4; in which the tie is extended to form a handle whcreb the radiator can be moved.

6. Means according to claim 4 in which the parts are combined with a cooking chamber having a slotted bottom, the radiator being Within the chamber with the tubular branch extending through the slot in the bottom and the hollow member and associated parts being arranged beneath the bottom.
